A Superelastic Retrofitting Method for Mitigating the Effects of Seismic Excitations on Irregular Bridges [PDF]
Civil Engineering Infrastructures Journal, 2018 Irregularities in bridge pier stiffness concentrate the ductility demand on short piers; while not operating on the longer and more flexible ones. The existence of non-uniform, ductility demand distribution in bridges significantly influences seismic ...

Modeling of Progressive Scouring of a Pier-on-Bank
CivilEng, 2022 Scour, caused by swiftly moving water, can remove alluvial sediment and soil, creating holes surrounding a bridge component and compromising the integrity of the bridge structure.

Ship-Bridge-Pier Protective Systems
Coastal Engineering 1980, 1980 This paper describes the analytical and experimental studies on the behaviors of a ship subjected to a sheering flow induced around a rectangular solid-type marine structure, and also deals with ship-structure protective systems against ship impacts. Large bridge piers, which are constructed in a narrow waterway with strong tidal currents, are treated ...

Expected seismic performance of irregular isolated bridges [PDF]
, 2012 Bridge structures are usually built on irregular topographical surfaces which create substructures with pier heights of different lengths. Three height irregularity types of typical RC medium length bridges are analyzed aimed at determining the best ...

Shaking Table Test of High Pier and Small Radius Curved Bridge under Multi-point Excitation
Advances in Civil Engineering, 2021 The non-uniform stratum and uneven surface have the complicated seismic spatial variability. The seismic response of high pier and small radius curved bridge caused by the seismic specificity of this kind of terrain has not been systematically studied ...

Mechanical Analysis of Junction Pier of Fuzhou-Xiamen High-Speed Railway Rigid-Frame Bridge
Advances in Civil Engineering, 2023 The continuous rigid structure bridge on both sides of the Quanzhou Bay Crossing Bridge uses double-limbed thin-walled flexible piers for the junction piers between the links, and the whole bridge has no bearings.
